Profiled web for venting and draining floor tiles, particularly ceramic tiles, laid in a thin retaining layer
First Claim
1. A profiled web for arrangement between the underside of floor tiles and an upper surface of a support plate, the profiled web comprisinga rigid plastic film formed to comprise a parallel series of successive channels, each of said channels being defined by first and second edge portions and a trough portion therebetween, the series of channels open alternately, as a first group of channels, to the upper surface of the support plate when in an installed position, and as a second group of channels to the underside of the floor tiles when in an installed position, trough portions of the channels open to the support plate when in an installed position being parallel and forming an upper surface of the web, and trough portions of the channels open to the tiles when in an installed position being parallel and forming a lower surface of the web, wherein the web is provided with a plurality of through-openings which produce a liquid- and gas-permeable connection between successive channels, anda substantially flat profile strip, extending transversely to the channels, adjacent longitudinal ends of the channels.

Abstract
A profiled web for arrangement between the underside of floor tiles and an upper surface of a support plate. The profiled web is based on a rigid plastic film formed to have a parallel series of successive channels, each of the channels being defined by first and second edge portions and a trough portion therebetween. The series of channels are open alternately to the upper surface of the support plate as a first group of channels and to the underside of the floor tiles when in an installed position as a second group of channels. First trough portions of the channels open to the support plate are parallel, and form an upper surface of the web; second trough portions of the channels open to the tiles are parallel and form a lower surface of the web. The web is provided with a plurality of through-openings which produce a liquid- and gas-permeable connection between successive channels. A liquid- and gas-permeable textile mesh is adhesively laminated to the upper surface of the web and extends across successive channels in the form of a plane. In an alternate embodiment, a supporting profile strip is located in transverse orientation to the channels, at the longitudinal ends of the channels.

17. A profiled web for arrangement between the underside of floor tiles and an upper surface of a support plate, the profiled web comprising
a rigid plastic film formed to comprise a parallel series of successive channels, each of said channels being defined by first and second edge portions and a trough portion therebetween, the series of channels being open alternately to the upper surface of the support plate as a first group of channels and to the underside of the floor tiles when in an installed position as a second group of channels, first trough portions of the channels open to the support plate when in an installed position being parallel and forming an upper surface of the web, and second trough portions of the channels open to the tiles when in an installed position, being parallel and forming a lower surface of the web, wherein the web is provided with a plurality of through-openings which produce a liquid- and gas-permeable connection between successive channels, and a liquid- and gas-permeable textile mesh, adhesively laminated to the upper surface of the web, and extending across successive channels in the form of a plane, wherein channels in the second group of channels are interrupted by transverse channels open to the underside facing the support plate when in the installed position.

32. Floor covering comprising floor tiles retained adhesively on at least one profiled web, said at least one profiled web being loosely placed on a support plate, said at least one profiled web comprising a rigid plastic film formed to comprise a parallel series of successive channels, each of said channels being defined by first and second edge portions and a trough portion therebetween, the series of channels open alternately to the upper surface of the support plate and to the underside of the floor tiles, trough portions of the channels open to the support plate being parallel and forming an upper surface of the web, and trough portions of the channels open to the tiles being parallel and forming a lower surface of the web, wherein the web is provided with a plurality of through-openings which produce a liquid- and gas-permeable connection between successive channels, and
a substantially flat profile strip, extending transversely to the channels, adjacent longitudinal ends of the channels.
